android 如何改变背景图片的大小 xml

Question

我正在为可绘制对象制作图层列表... 我想设置笔触（2dp，颜色：#000000），角（5dp），背景（黄色）并在右侧添加图像，但我无法更改图像大小。

我想要什么：

但我有类似的东西:

这是我的代码： content_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="info.e_konkursy.myapplication.MainActivity"
    tools:showIn="@layout/app_bar_main">


    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TableRow
            android:layout_width="200dp"
            android:layout_height="20dp"
            android:background="@drawable/bg_tablerow11"
            android:padding="10dp">

            <TextView
                android:id="@+id/textView2"
                android:layout_width="100dp"
                android:text="@string/country"
                android:textAppearance="?android:attr/textAppearanceMedium" />

            <TextView
                android:id="@+id/textView3"
                android:layout_width="150dp"
                android:layout_height="20dp"
                android:text="Poland"
                android:textAppearance="?android:attr/textAppearanceMedium" />
        </TableRow>
    </TableLayout>
</RelativeLayout>

bg_tablerow11.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:layout_width="10dp"
        android:layout_height="10dp"
        android:drawable="@drawable/arrow"
        android:gravity="right" />
    <item>
        <shape
            android:padding="10dp"
            android:shape="rectangle">
            <stroke
                android:width="2dp"
                android:color="#000000" />
            <corners
                android:bottomLeftRadius="5dp"
                android:bottomRightRadius="5dp"
                android:topLeftRadius="5dp"
                android:topRightRadius="5dp" />
        </shape>
    </item>

</layer-list>
